I always enjoy attending OSCON (I've been to all of them--scary!), and this year was no exception. The talks I attended easily held my interest and the people, as always, were top-notch. Lots of good geek-out time was had by all.

And giving out YDN t-shirts at the Yahoo! booth meant getting a chance to find out what people do and don't know about the APIs we offer. In fact, I made a point of quizzing booth visitors to see which Yahoo! APIs they knew of. Our Maps and Geocoding APIs were especially popular.

But I surprised people most often with YUI, our BSD Licensed User Interface library. Each time I'd describe some of the cool things you can do with it and someone would say, "that's great... but are you actually using it on Yahoo?"
